Abstract (en)
[origin: EP0718478A1] The exhaust gases from a diesel engine are treated to remove nitrous oxides. Treatment occurs in a catalytic converter (12) positioned in the inlet to the exhaust pipe (8a). The catalyst is surrounded by a gas collection chamber (3) which contains an adsorber (15) of oxides of nitrogen. Exhaust gases circulate turbulently through this chamber in contact with the adsorber, then pass through the catalyst.
